Giant Mushroom Popover: A Savory Delight

There’s something magical about watching a popover rise in the oven, ballooning into a golden, airy cloud. My grandmother used to make them every Sunday, the aroma filling her cozy kitchen with warmth. While hers were often sweet, dusted with powdered sugar, I’ll never forget the day she experimented with a savory version, packed with earthy mushrooms. That first bite – the crisp exterior yielding to a soft, mushroom-infused interior – was a revelation. This recipe is my homage to that moment, a celebration of simple ingredients transformed into something truly special.

Recipe Overview

Prep Time: 15 minutes
Cook Time: 30-35 minutes
Total Time: 45-50 minutes
Servings: 3
Dietary Type: Vegetarian

Ingredients

1 tablespoon butter
½ cup finely minced onion
½ lb fresh domestic mushrooms, stemmed and thinly sliced
¼ lb fresh shiitake mushrooms, stemmed and minced
1 large garlic clove, minced
¾ teaspoon salt
2 tablespoons dry sherry
3 large eggs
1 cup milk
1 cup unbleached white flour

Equipment Needed

10″ ovenproof skillet
Blender
Measuring cups and spoons

Instructions

Preheat your oven to 375°F (190°C). It’s crucial to have the oven fully heated before you start baking, as the high heat is what makes the popover rise.
Melt the butter in a 10″ ovenproof skillet over medium heat. Make sure the skillet is truly ovenproof; some skillets have handles that can’t withstand high oven temperatures.
Add the finely minced onion to the melted butter and sauté over medium heat for about 5 minutes, or until softened and translucent. Sautéing the onion brings out its sweetness and creates a flavorful base for the mushrooms.
Stir in the sliced domestic mushrooms, minced shiitake mushrooms, minced garlic, and salt. Sauté for another 5 minutes, stirring occasionally, until the mushrooms begin to release their moisture and soften.
Add the dry sherry to the skillet and cook, uncovered, for 10 minutes longer. The sherry adds a depth of flavor and helps to deglaze the pan, lifting up any browned bits from the bottom. The aroma at this stage is simply divine!
While the mushrooms are cooking, prepare the batter. In a blender, combine the eggs, milk, and flour.
Whip the ingredients in the blender until you have a smooth batter, free of any lumps. Over-mixing can develop the gluten in the flour, resulting in a tougher popover. So, blend just until everything is combined.
Pour the batter evenly over the mushroom mixture in the skillet. Be careful not to splash the hot mixture.
Transfer the skillet to the center rack of the preheated oven.
Bake for 25-30 minutes, or until the popover is set and golden brown. The popover should be puffed up and lightly browned. Avoid opening the oven door during baking, as this can cause the popover to deflate.
Once the popover is done, remove it from the oven.
Cut the giant mushroom popover into wedges and serve hot or warm. Enjoy!

Expert Tips & Tricks

Room Temperature Ingredients: Using room temperature eggs and milk can help the popover rise more evenly. Take them out of the refrigerator about 30 minutes before you start cooking.
Hot Skillet: Ensure the skillet is hot before pouring in the batter. This initial heat helps to create the steam necessary for the popover to rise properly.
Don’t Peek! Resist the urge to open the oven door while the popover is baking. The sudden temperature change can cause it to collapse.
Alternative Mushrooms: Feel free to experiment with different types of mushrooms, such as cremini, oyster, or portobello, to create your own unique flavor profile. Just be sure to adjust cooking times as needed, as some mushrooms release more moisture than others.
Make-Ahead Component: The mushroom mixture can be prepared a day in advance and stored in the refrigerator. Bring it to room temperature before adding the batter and baking.
Sherry Substitute: If you don’t have dry sherry on hand, you can substitute with dry white wine or chicken broth.
Troubleshooting: If your popover is not rising, make sure your oven is hot enough and that you are not opening the oven door during baking. Also, ensure that your batter is smooth and that the eggs and milk are at room temperature.

Serving & Storage Suggestions

Serve your giant mushroom popover immediately for the best texture and flavor. The crisp exterior softens as it sits. A dollop of sour cream or crème fraîche complements the savory mushrooms beautifully. It also pairs well with a side of roasted asparagus or a simple green salad for a complete and satisfying meal.

Leftover popover can be stored in the refrigerator for up to 2 days. To reheat, place a wedge in a preheated 350°F (175°C) oven for about 5-10 minutes, or until warmed through. You can also reheat it in a microwave, but the texture will be softer. Freezing is not recommended as it affects the texture significantly.

Variations & Substitutions

Gluten-Free: Substitute the unbleached white flour with a gluten-free all-purpose flour blend. You may need to add a bit more liquid to achieve the right batter consistency.
Dairy-Free: Use a plant-based milk alternative, such as almond milk or soy milk, in place of the cow’s milk. You can also use olive oil instead of butter for sautéing the vegetables.
Herbaceous Twist: Add fresh herbs, such as thyme, rosemary, or parsley, to the mushroom mixture for added flavor.
Spicy Kick: Add a pinch of red pepper flakes to the mushroom mixture for a subtle heat.
Cheese Lover’s Delight: Sprinkle some grated Parmesan cheese over the popover during the last few minutes of baking for a cheesy, savory crust.

FAQs (Frequently Asked Questions)

Q: Can I make this popover in a different sized skillet?
A: While a 10″ skillet is ideal, you can use a slightly smaller or larger skillet. Keep in mind that a smaller skillet will result in a thicker popover, which may require a longer baking time. A larger skillet will result in a thinner popover, which may bake faster.

Q: Why did my popover deflate after I took it out of the oven?
A: Popovers can sometimes deflate slightly after being removed from the oven. This is normal and is due to the steam inside the popover cooling down. To minimize deflation, try not to open the oven door during baking and serve the popover immediately after removing it from the oven.

Q: Can I use dried mushrooms instead of fresh?
A: While fresh mushrooms are preferred for their texture and flavor, you can use dried mushrooms in a pinch. Rehydrate the dried mushrooms in hot water before adding them to the skillet. Be sure to drain them well. Reduce the salt content in the recipe if using dried mushroom as they can be quite salty.

Q: Is it necessary to use a blender to make the batter?
A: While a blender is the easiest way to achieve a smooth batter, you can also use a whisk. Just make sure to whisk the ingredients thoroughly to remove any lumps.

Q: Can I add other vegetables to the mushroom mixture?
A: Absolutely! Feel free to add other vegetables, such as bell peppers, zucchini, or spinach, to the mushroom mixture. Just be sure to adjust cooking times as needed.
